Default Behavior

The File System Dependency Minifilter service is a file system driver. In Windows 8 it will not be started until the user starts it. If File System Dependency Minifilter fails to load or initialize, the error details should be automatically logged. Then Windows 8 is restarting the PC and attempting to use the Last Known Good configuration. If the Last Known Good configuration isn't working properly, Windows 8 startup ends with a Stop error. If you disable the FsDepends service, Windows 8 will fail to start.


File System Dependency Minifilter can't start, if the FltMgr service is disabled or not available.
